Scientists detected seismic waves showing Mars cycles rock through its mantle like Earth does, meaning both planets refresh their crusts. The real question: if a dead planet does this automatically, why do we treat Earth's finite resources as infinite?
Mars seismic data reveals mantle convection, same process that recycles Earth's oceanic crust continuously.
Both planets lose heat and material to space, yet both maintain geological renewal for billions of years.
Human economy treats extraction as linear: take, use, discard. Geology treats it as circular by necessity.
